摘要： A loading unit assembly includes a shell assembly and a locking collar. The shell assembly has a proximally extending annular ring that defines a cylindrical opening. The annular ring defines a lock opening that passes through the annular ring. The shell assembly defines a retention slot that is adjacent the annular ring on an opposite side of the annular ring from the lock opening. The locking collar is positioned about the annular ring and has a body, a lock, and a retention tab. The body includes a release surface. The locking collar has a locked configuration wherein the lock extends into the cylindrical opening and an unlocked configuration wherein the lock is disposed outwardly of the cylindrical opening. The side of the locking collar opposite the lock is prevented from moving outwardly in relation to the annular ring when the release surface is pressed inwardly towards the annular ring.

摘要： A retaining mechanism for releasably securing a trocar assembly within an outer sleeve of an adapter assembly includes a retaining block, a cam wire moveably positioned relative to the retaining block between a lock position and a release position, a retaining block extension maintaining the cam wire relative to the retaining block, a button member in operable engagement with the cam wire, and a pair of retaining members moveable from a first position received within first and second openings of the trocar assembly when the cam wire is in the lock position and a second position spaced from the trocar assembly when the cam wire is in the release position. The retaining members each define a cutout having first and second stepped cutout portions and a smooth transition between the first and second stepped cutouts for receiving the cam wire.
